My suggestion was to check if memory initialization can not rather be done _without_ reading (and without otherwise knowing) the board type or revision. Usually this is possible, and I always prefer such auto-adjusting solutions over hard-wired approaches that break down when any of the expected inout data is not correct or not available.
